Advanced Settings
The Advanced Settings are used for parameters that are either rarely modified or
which are only used for debugging purposes.
Arc Resolution - the Edge rasterizer must first unionize the Gerber input data prior to
rasterizing it. This requires converting all curves into segments. The
resolution can be controlled by this parameter - the value is the arc subtended
by each segment in degrees.
Chord Error - the Edge rasterizer must first unionize the Gerber input data prior to
rasterizing it. This requires converting all curves into segments. The
resolution can be controlled by this parameter.
In this case, for each arc, the program computes the number of segments needed
to approximate it based on the maximum difference between the arc and its
approximation.
This means that arcs of larger radius need more segments.
Chord Error is often referred to as Arc Sag.
Thread Number - parts of the Edge Rasterizer can be multi-threaded. This parameter controls
the number of threads (Note: to use additional threads requires additional
memory bitmap buffers -- unless more memory is available extra threads will not
help.)
Boolean Additional Arguments - allows a user to inject additional arguments into the boolean engine. Only for
debugging purposes.
Striping - controls how a large file is subdivided into sections in order to prevent a
exponential growth in processing time. This is normally computed automatically
and not under user control.
Droplet Additional Arguments - allows a user to inject additional arguments into the dropletplacement engine.
Only for debugging purposes.
